TOMZN TOVPD1-60-EC is a multifunctional protection relay designed for single-phase electrical systems, offering integrated over-voltage, under-voltage, and over-current safeguards. Its primary advantage over standard, non-adjustable protectors is its deep level of customization, allowing users to fine-tune thresholds to suit specific local power conditions. Core Technical Capabilities The device is rated for at 50/60Hz and can handle loads up to
Step 1: Location
Install the TOVPD160EC on a DIN rail inside your main distribution board (MDB). It requires 4 standard modular spaces (72mm). Ensure it is downstream of your main isolator but upstream of individual circuits.
- Turn off your main breaker (simulate a blackout).
- Turn it back on.
- Does the TOVPD160EC count down and reconnect? If yes, it is healthy.

- Adjust using +/-.
- Better setting: 265V – 270V. (Grid voltage can spike to 250V normally. If set to 240V, it will nuisance trip).
